Unfortunately, this level doesn't really provide enough granularity. We
probably need several MI NOTES type files for things that are shared by
several architectures but not by all. For example, the PCI options could
live in a NOTES.pci.
This also updates the Makefile for i386 to generate LINT. The only changes
in the generated LINT are the order of various options.
Suggestions for improvement welcome.
in dump byte order (=network byte order). Swap blocksize and dumptime
to avoid extraneous padding on 64-bit architectures. Use CTASSERT
instead of runtime checks to make sure the header is 512 bytes large.

emitted the total number of pages it still had to dump prior to
dumping a block of up to 16 pages. For a 128MB region this would
result in 8M number of printf()s. Barf!
The problem in general is that memory typically has one really
big region and a number of "scattered" smaller regions. Some may
even be just a few pages. The twiddle works best for now, but
it doesn't really give a good progress indication for the large
regions. Those are the cases where you definitely want good PI
to avoid having the user turn into a twiddle :-)
without removing the buffer from the vnode's dirty buffer list, which
can result in a panic in NFS. Replaced the code with a call to bundirty()
which deals with it properly.

Didn't really test on ia64 or i386- don't have the former h/w and my

Besides, the previous implementation (using linear probing) was broken :)

- Add a new function mutex_init() used to perform early initialization

to call this function instead of duplicating all the code themselves.

locks to be able to setup a SYSINIT call. This helps in places where
a lock is needed to protect some data, but the data is not truly
associated with a subsystem that can properly initialize it's lock.
The macros use the mtx_sysinit() and sx_sysinit() functions,
respectively, as the handler argument to SYSINIT().

presented in microseconds, which should be sufficient for the locks for

Also, rename some variables and structure members to unit-agnostic names.
